I’m on a day trip with friends and she texted me that before I had left for it. What does she mean? Don’t cheat?

How is that unclear?

If it is why wouldn't you ask for clarity from the source?

No mess with other women.

Don’t flirt with other women as she “would not do.”

It's an expression. That's it
